Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic heating equipment, and in particular to a power distribution method, electromagnetic heating equipment and electronic equipment. Background Art

[0002] There are many types of multi-burner induction cookers. In one type, the sum of the maximum power allowed for each burner is greater than or equal to the maximum power of the entire cooker (for example, a single burner has a maximum power of 2100W, while the total power is 2200W). When multiple burners are operating simultaneously, the burner power must be controlled to ensure that the total power does not exceed the maximum power of the entire cooker. When the burners are operating, the multi-burner induction cooker's control panel calculates and allocates the target power or target gear (the gear has a predetermined power level) based on user input and directly sends the target power or target gear to each burner. Each burner's heating plate then operates at its own target power.

[0003] However, due to the complexity of the working conditions of multi-burner induction cookers, after the target power of each burner is allocated on the operation panel, the burner will actively adjust the power range according to different working conditions parameters such as temperature, voltage, and cookware during heating to ensure the reliability and stability of the multi-burner induction cooker. When the burner works according to the adjusted power range, it is possible that the sum of the target power of each burner exceeds the maximum power of the entire machine. Summary of the Invention

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] like Figure 1 As shown, the power allocation method according to an embodiment of the present invention includes:

[0037] Step S100, obtaining the whole machine power, which is the maximum power allowed for the electromagnetic heating device to operate;

[0038] Step S200: acquiring a first power range of the heating module 200 in real time, where the first power range is a power range within which the heating module 200 is allowed to operate;

[0039] Step S300: determining the target power of the heating module 200 according to the entire machine power and the first power range, wherein the target power is within the first power range and the sum of the target powers of the various heating modules 200 does not exceed the entire machine power;

[0040] Step S400 : Allocate target power to the heating module 200 .

[0041] By acquiring the total system power, the first power range of the heating module 200 is obtained in real time. The target power of the heating module 200 is determined based on the total system power and the first power range. If the target power falls within the first power range, the sum of the target powers of each heating module 200 does not exceed the total system power. The target power is then allocated to the heating modules 200, and the heating modules 200 operate according to the target power. Compared to existing power allocation methods, the power allocation method according to an embodiment of the present invention acquires the first power range of the heating module 200 in real time, calculates the target power of each heating module 200 based on the first power range, ensures that the sum of the target powers of each heating module 200 does not exceed the total system power, and then issues the target power to each heating module 200 for execution. This prevents the sum of the target powers of each heating module 200 from exceeding the total system power due to adjustments to the first power range.

[0042] like Figure 2 As shown, in one embodiment of the present invention, in step 300, the target power of the heating module 200 is determined according to the whole machine power and the first power range, and further includes:

[0043] Step S310: obtaining the rated voltage of the electromagnetic heating equipment;

[0044] Step S320: acquiring the grid voltage in real time, and obtaining the second power range according to the grid voltage, the rated voltage, and the first power range;

[0045] Step S330: determining the target power of the heating module 200 according to the entire machine power and the second power range.

[0046] In this step, the rated voltage of the electromagnetic heating equipment is obtained, the grid voltage is obtained in real time, the first power range is adjusted according to the grid voltage to obtain the second power range, and then the target power of the heating module 200 is determined according to the second power range and the power of the whole machine. Since the real-time grid voltage of the heating module 200 is combined, the second power range is more suitable for the working condition of the heating module 200 than the first power range, so that the target power suitable for the working condition of the heating module 200 can be accurately determined according to the second power range.

[0047] like Figure 3 As shown, in one embodiment of the present invention, in step S320, obtaining the second power range according to the grid voltage, the rated voltage and the first power range includes:

[0048] Step S321: If the grid voltage is higher than the rated voltage, obtain the lower limit of the second power range according to the grid voltage, the rated voltage, and the lower limit of the first power range;

[0049] Step S322: Obtain an upper limit value of the second power range according to the grid voltage, the rated voltage, and the upper limit value of the first power range.

[0050] In this step, the upper limit value of the first power range and the lower limit value of the second power range are precisely adjusted according to the grid voltage and the rated voltage to obtain the second power range, so that the target power determined according to the second power range is more suitable for the current working condition of the heating module 200.

[0051] In one embodiment of the present invention, in step S321, the lower limit value of the second power range is obtained by the following formula: Pmin=P1+a(V1-V2), where Pmin is the lower limit value of the second power range, P1 is the lower limit value of the first power range, a is the power adjustment coefficient, V1 is the grid voltage, and V2 is the rated voltage.

[0052] During the operation of the heating module 200, the grid voltage will fluctuate in real time. If the grid voltage is higher than the rated voltage and the heating module 200 operates at a lower target power under a higher grid voltage, the heating module 200 is easily damaged. In this step, the above formula can be used to adjust the lower limit of the second power range in combination with the real-time grid voltage to prevent the heating module 200 from operating at a lower target power, thereby playing a protective role.

[0053] In one embodiment of the present invention, in step S322, the upper limit value of the second power range is obtained by the following formula: Pmax=P2-a(V1-V2), where Pmax is the upper limit value of the second power range, P2 is the upper limit value of the first power range, a is the power adjustment coefficient, V1 is the grid voltage, and V2 is the rated voltage.

[0054] During the operation of the heating module 200, if the grid voltage is higher than the rated voltage and the heating module 200 is operating at a higher target power, it is easy for the sum of the target powers of each heating module 200 to exceed the power of the entire machine, damaging the electromagnetic heating equipment. The above formula can be used to adjust the upper limit value of the second power range in combination with the real-time grid voltage to prevent the heating module 200 from operating at a higher target power, thereby playing a protective role.

[0055] like Figure 4 As shown, the electromagnetic heating device according to an embodiment of the present invention includes: a control module 100, multiple heating modules 200, a grid voltage detection module 300 and a current detection module 400. The output end of the control module 100 is connected to the control end of the heating module 200. The control module 100 distributes power to the heating module 200 by executing the above-mentioned power distribution method. The output end of the grid voltage detection module 300 is connected to the input end of the control module 100. The grid voltage detection module 300 is used to detect the grid voltage. The output end of the current detection module 400 is connected to the input end of the control module 100 for detecting the current of the heating module 200.

[0056] By acquiring the total power of the heating module 200, the first power range of the heating module 200 is acquired in real time. The target power of the heating module 200 is determined based on the total power and the first power range. The target power is within the first power range, and the sum of the target powers of the various heating modules 200 does not exceed the total power of the heating module. The target power is then distributed to the heating modules 200, and the heating modules 200 operate according to the target power. According to an embodiment of the second aspect of the present invention, the electromagnetic heating device acquires the first power range of the heating module 200 in real time, calculates the target power of each heating module 200 based on the first power range, ensures that the sum of the target powers of each heating module 200 does not exceed the total power of the heating module, and then issues the target power to each heating module 200 for execution, thereby preventing the sum of the target powers of each heating module 200 from exceeding the total power of the heating module due to adjustment of the first power range.

[0057] In one embodiment of the present invention, the heating module 200 includes a PPG driving module and a resonant heating module 200 , the output end of the control module 100 is connected to the control end of the PPG driving module, and the output end of the PPG driving module is connected to the control end of the resonant heating module 200 .

[0058] The control module 100 obtains the grid voltage through the grid voltage detection module 300, obtains the current of the heating module 200 through the current detection module 400, and calculates the real-time power of the heating module 200 based on the grid voltage and current. If the real-time power does not match the target power, the power of the resonant heating module 200 is adjusted through the PPG drive module to ensure that the working power of the heating module 200 is stable.

[0059] In one embodiment of the present invention, a temperature detection module 500 is further included. The output end of the temperature detection module 500 is connected to the input end of the control module 100. The temperature detection module 500 is used to detect the temperature of the heating module 200. The temperature detection module 500 can detect the temperature of the heating module 200 in real time, and the control module 100 can adjust the power of the heating module 200 according to the temperature.

[0061] By acquiring the total power of the heating module 200, a first power range of the heating module 200 is acquired in real time. The target power of the heating module 200 is determined based on the total power and the first power range. Within the first power range, the target power is such that the sum of the target powers of the various heating modules 200 does not exceed the total power of the heating module. The target power is then distributed to the heating modules 200, and the heating modules 200 operate according to the target power. An electronic device according to an embodiment of the third aspect of the present invention acquires the first power range of the heating module 200 in real time, calculates the target power of each heating module 200 based on the first power range, ensures that the sum of the target powers of each heating module 200 does not exceed the total power of the heating module, and then issues the target power to each heating module 200 for execution, thereby preventing the sum of the target powers of the various heating modules 200 from exceeding the total power of the heating module due to adjustment of the first power range.
